Learn about the culture of aquatic organisms with Aquaponics - an exciting blend of Hydroponics and Aquaculture.

Special Offer - Reduced course price plus 6 free eBooks when you enrol.

Aquaponics is the combination of hydroponics with aquaculture in controlled environment, whereby fish waste provides a source of nutrients for plants, and the plants, in turn, provide a filter for the water in which the fish live.

Aquaponics is considered the world’s most productive food system with regards to water use efficiency. Many aquaponics systems only use around half of the volume of water to produce £100 worth of food (fish and vegetables or fruit) than inorganic hydroponics.

Aquaponics is an intensive way of farming that can be conducted anywhere.

  • It can produce a great deal more food products per unit of area than more traditional forms of farming.
  • It diversifies the income for a grower, making them more resilient to fluctuations in income (e.g. when vegetables are in less demand, fish might be in higher demand. If fish profits drop, vegetable profits may increase).
  • It can be viable on any scale, small scale set ups in small home garden can provide for the needs of a single family, while medium size operations on less than a quarter acre can be a viable small business, and large scale operations on many acres, even hundreds of acres can form the heart of a larger business enterprise.
  • It can allow food to be produced closer to the end user in areas otherwise unsuited to farming (e.g. in a desert, in inland city areas, etc.). This reduces food miles, expenditure of fuel on food transport, reduces potential pollution, and in turn increases the freshness of food arriving at market.
  • It can be more efficient use of water where water resources are limited.
  • It can be environmentally friendly, containing and reusing waste, rather than returning it to the environment, and causing pollution.

THE AQUAPONICS SYSTEM

Aquaponic systems can vary greatly in size. They can be as small as an indoor fish tank or a large scale commercial aquaponics system. The type and size of aquaponics system you choose will affect the components and features that you will need to run it. Generally, the main components of any aquaponics system are:

  • Grow beds.
  • Fish Tank.
  • Fingerlings Tank.
  • Water Pump.
  • Air Pump.

To ensure that a system is functioning at an optimal rate the water temperature, pH, dissolved oxygen, nutrients, salinity, ammonia and nitrite need to be within appropriate levels.

Water temperature – this is vital to the survival of fish. Temperature fluctuations outside of the normal range for fish species can induce shock in fish and possibly lead to death. The climate of your region will influence the heating and cooling you will need.

pH – measure of how acidic or basic the water is. The pH level is usually higher at the beginning of a cycle and then gradually decreases once a system has cycled completely. In general the pH should be between 6.8 and 7.2.

Dissolved Oxygen – dissolved oxygen is required by all fish to survive. The water properties and stocking densities will affect its ability to hold oxygen. For example, warmer water will hold less oxygen.

Nutrients – macro and micro nutrients are needed for healthy plant growth. Plants can grow with limited nutrients, however this will affect their appearance and flavour. They may also be more susceptible to disease without adequate nutrients.

Salinity – non-iodized sea salt is used as macro nutrients and for treating any diseases in fish.

Ammonia – this the first product of the nitrogen cycle. There are two forms of ammonia, unionized ammonia is most toxic to fish.

Nitrite – this is the second product of the nitrogen cycle. Nitrite is produced by the oxidation of ammonia by bacteria and is highly toxic.

Check out our eBooks

Aquaponics eBookThe Aquaponics ebook will give you a great understanding of how to start your own aquaponics production. This 65 page ebook provides you with enough information to start your own home production and even manage issues as they arise. This is a great way to become more self-sufficient and produce a sustainable food source for your own household. Aquaponic farming allows individual families to grow a much wider range of produce, in a much smaller space. They can provide the protein needed for their diet (from fish), as well as the vegetables and fruit they need. Aquaponic systems can be as small as a few cubic meters; or as large as many acres. They are an ideal way of improving productivity on a hobby farm; can be used by restaurants to produce the freshest produce on site, or established inside buildings, in big cities, for urban farming.
Fish for Freshwater Aquaculture and AquaponicsChoosing the most suitable fish for any fish farm or aquaponics system is a very important decision. Some fish species are easier to grow, some are more profitable to grow, and some suit a particular approach to fish culture better than others. Whether operating on a large or small scale; making the right choice of fish type can be the most critical decision, and this is the book to help you make that decision. Suitable for amateurs and professionals, a great overview for students or anyone new to aquaculture; inspiring and revealing for farmers who are thinking of stocking a dam, through to home owners considering re-purposing a swimming pool.
Commercial HydroponicsThe Commercial Hydroponics ebook is ideal for students, professional horticulturalists and those who want to build a strong foundation knowledge in hydroponics. The commercial hydroponics ebook explains how to set up a commercial hydroponics system, including growing techniques and equipment that you will need. The topics covered in this book include an introduction to hydroponics, site considerations, alternatives, plant nutrition, nutrient film technique culture, rockwool culture, aggregate culture, other techniques, hydroponics equipment, greenhouse operation, plant culture in hydroponics, Vegetable crops, berry and other fruit crops, flower crops, other crops, managing a commercial hydroponic farm and a troubleshooting guide.
